Application for LCGT membership Prof. Riccardo De. Salvo University of Sannio Benevento, Italy
The University of Sannio • University of Sannio group (prof. I. Pinto) has a history of collaboration with TAMA • Later joined LSC, working on Data analysis and on mirror development (in collaboration with me)
The University of Sannio (2) • With the start of LCGT the Sannio group is re-organizing to support LCGT • Initially with mirror coating, mechanics, controls, eventually with data analysis • The group will formally apply in the next few months • The mechanics contribution is urgent • => Individual pre-application to LCGT
What about me, and why LCGT • I am a physicist loves to work with new technologies and do precision engineering • I have a string of achievements in many areas of experimental physics • I have already contributed with TAMA-SAS • I like to work with, and train young scientists • It would be a great privilege to contribute my work to make LCGT a success
Why join LCGT ? • It was great working in Japan for TAMA and with Kuraray and other Japanese projects. • LCGT selected SAS, one of my best concepts, of which I am very proud • LCGT is the first underground GW detector, leading to the 3 rd generation, and it is a great new challenge ! !
What can I do for LCGT • I spent 15 years perfecting the SAS technique and understanding the behavior of the necessary materials • I’d like to put this effort to good use • My most important contribution to LCGT would therefore be to develop and implement its SAS seismic isolation, working with Takahashi
What else can I do for LCGT • I have : – Experience in Vacuum techniques – Experience with mirror and coating development (Pinto, Mexican hat interferometer) – Considerable experience with underground operations. I am the son of a miner, I worked extensively in tunnels in CERN and Fermilab, and most recently in DUSEL and fully appreciate the problems involved.
What can I bring to LCGT • I worked in Virgo and LIGO as they developed • I learned what was relevant and what’s not • I can contribute this experience • I started studying the problems of third generation observatories (DUSEL-ET) – e. g. the xylophone concept • I can help LCGT to become the 3 rd generation pathfinder
What else can I bring to LCGT • I enjoy collaborations and I have always worked with a wide variety of scientists • Hearing that I may join LCGT, a number of scientists from Italy, Netherlands and the US have already expressed a desire to collaborate with me in LCGT
What can I do besides LCGT • I have R&D ideas about improving material performance both in springs and coatings • During my life I dealt with ~ 100 students and young scientists, some Japanese • I can suggest student thesis projects and mentor them
Conclusion • It would be a great privilege for me to be accepted into the LCGT team
My academic and research history • 1979 Atomic spectroscopy master thesis at University of Pisa on super-radiant pulses in Cs (building lasers, tests on laser assisted gene splitting) • 1980 Apply for graduate studies – Accepted to Ecole Normale Superieure de Paris – Instead, I was directly offered an unsolicited research fellowship (postdoc) at CERN • (I became the youngest postdoc at CERN)
CERN postdoc (1980 -1983) • Built lasers for calibration of drift chambers • In charge of the beam detectors of the SPS experimental halls (~ 1000 photomultipliers) • Developed drift chambers for luminosity monitor and p-pbar cross section measurement at SPS collider • I built the apparatus for Jim Cronin’s lifetime experiment
Cornell postdoc/staff scientist (19841987) • Design/build large collider drift chamber • Design/build elastic scattering experiment at Fermilab • Design/build CESR Beryllium pipe/vertex drift chamber collision region • Contributed tracker designs for SSC and CEBAF
CERN staff scientist (1988 -1993) • Spaghetti calorimetry development program – Development of scintillating/wavelength shifting fibers with Kiowa-gas/Kuraray • Invention/development of Hybrid Photo Diode – (Work also with Hamamatsu) • Quartz fiber calorimetry development • Work on avalanche photo diodes – It explains why CMS e. m. calorimeter has false readings
Switch to Gravitational Waves (1994) • I returned to Italy • I chose to work at Virgo on the fascinating and challenging field of Gravitational Wave Detection
Virgo INFN scientist (1994 -1997) • Design/Prototype the superattenuators – Introduce maraging for springs – Eliminate shear clamps • Design/Prototype accelerometers • Some interest in vacuum pipe & baffle design
LIGO Caltech scientist (1998 -2010) • Develop GAS filters and SAS structure • Design Hongo-SAS and TAMA-SAS (Takamori) • Design/Build/test HAM-SAS • Provide design for AEI-SAS and NIKHEF-SAS for Virgo
LIGO Caltech scientist (1998 -2010) • Mesa beam experiment to reduce mirror thermal noise • Design of optimized coating mirrors (Pinto) • Directional radiative cooling (Kawamura-kun)
LIGO Caltech scientist (1998 -2010) • Identified problem with mechanical noise from SOC of dislocations • Work on glassy metal springs/flexures • Work on creep • Development of techniques for third generation, experience in underground GW observatories, NN subtraction, . . . • Serve on Vacuum Review board
Publications • I have written or contributed to 270+ publications, most on refereed scientific journals • I have two patents • I am editing a book on Optical coatings
